According to the prosecutor's office, the request was filed under a bilateral Sweden-Ecuador agreement on legal cooperation, signed in late 2015.
"We will cooperate with the Swedish authorities so they can take some statements. We have said that from the beginning," Patino said as quoted by RTE News on Wednesday, adding that Ecuadorian prosecutors would be the ones carrying out the questioning in the presence of Swedish prosecutors.
Assange launched the WikiLeaks website in 2006. He has been residing at the Ecuadorian Embassy in London since 2012, out of fear of being extradited, first to Sweden where he has been accused of sexual assault, and ultimately to the United States where he could face espionage charges for publishing secret documents through his website.
